LATENCY DELAY OF THE VASTUS MEDIALIS OBLIQUE AND VASTUS LATERALIS IN INDIVIDUALS WITH PATELLOFEMORAL PAIN SYNDROME

open access: yes, 2016
Purpose: To determine the onset latency of the vastus medialis oblique (VMO) and vastus lateralis (VL) muscles in individuals with patellofemoral pain syndrome (PFPS). Methodology: A case-control study. Fourteen female participants with PFPS and fifteen female participants without PFPS performed a sudden lower extremity perturbation test in anterior ...

A cadaver study of the function of the oblique part of vastus medialis [PDF]

open access: yesThe Journal of Bone and Joint Surgery. British volume, 1995
Six normal cadaver lower limbs were mounted on a specially designed loading apparatus. Wires were used to simulate the five muscle bellies of the quadriceps, the ratio of their tensions having been determined from that of the anatomical cross-sectional areas of the muscles. A three-camera system was used to track the patella during knee movements from

The Effect of Patellofemoral Pain Syndrome in Athletes on Electromyographic Activity Ratio of Patellar Stability Muscles during Maximum Voluntary Isometric Contraction [PDF]

open access: yesSport Sciences and Health Research, 2013
Patellofemoral pain syndrome is a common condition athletes suffer from. One of the predictive factors of this syndrome is reduced activity ratio of vastus medialis oblique (VMO) to vastus lateralis (VL).
